I have a divider circuit similar to a x10 scope probe.
I need a bandwidth of least 100MHz, preferably greater.
I am using through-hole MICA capacitors (1%). The capacitors have a low enough ESL that they should be adequate.
While laying out the board I had a thought.
If the capacitors are placed parallel to each other the B field should cancel out, making the inductance effectively zero (or closer to zero.)
This should improve the bandwidth of the divider circuit, right?
There is a resistor divider and a variable glass cap not show in the circuit below, but the basic idea is that in the RIGHT circuit any B field in 1 capacitor will induce an equal and opposite current in the second capacitor.
Am I right? Is this a technique for expanding the range of capacitors?
